Cheiloscopy: An evolving tool in forensic identification

Abstract

Cheiloscopy deals with the identification of humans based on lip traces. “Cheilos” is a Greek word meaning lip and “Scopy” means to examine. Human identification is one of the most challenging subjects. The lip print of every person is unique. The grooves present on the lips (sulci labiorum) are unique for every person and can be used in individual identification. In forensic identification, lip print pattern gives us important information and helps in individual identification. Lip prints are normal lines and fissures in the forms of wrinkles and grooves present in the zone of transition of human lip of inner oral labial mucosa and outer skin or vermilion border. The study of these grooves or furrows is known as cheiloscopy.
